Enhanced crystal network and charge transfer of non-fused ring electron acceptor via interchain interaction enable efficient and stable organic solar cells Non-fused ring electron acceptors (NFREAs) are regarded as the alternative materials for low-cost organic solar cells (OSCs), but their power conversion efficiencies (PCEs) lag behind those of fused ring counterparts.

Aggregation state tuning via controlling molecular weights of D-A1-A2 type polymer donors for efficient organic photovoltaics Shanlu Wang, Tianyi Chen, Shuixing Li, Lei Ye, Yuang Fu, Xinhui Lu, Haiming Zhu, Lijian Zuo, Minmin Shi and Hongzheng Chen Abstract Thiophene ring-based polymer donors generally face the challenges of high-lying energy levels and unfavorable aggregation state, thus limiting the performances of thiophene-based organic photovoltaics (OPVs).
